MACHINE FOR FIXIL TG CLASPS.

Specification of Letters Patent.

Patented July 1, 1919..

Application filed December 26, 1913. Serial No. 808,882.

To all 'wlwm'c't may concern:

O Be it known that'we, ALEXA nn'n BLU- tmnrrmr. and JACK BLUMENTHAL,subjects of the King of Great. Britain, both residing at-Paris, 32 RueBaudin, in the. Re ublic of France; engineers, have invente certain newand useful Improvements in Ma chines for Fixin Clasps, of which thefollowing is a speci cation.

This invention relates to a machine for fixing clasps on paper bags,cardboard boxesand anyother packets.

For such purpose, the machine comprises essentially a carrier for a'verythin anvil adapted to be inserted underneath the closing parts of thepacket, either in sliding be-' tween such parts or in perforating one ofthe said parts and in shdlng underneath the same. i

The anvil serving to bend or close the clasps is arranged on the end ofsuch carrier and may be constituted by such and or be secured thereto;the essential point is that it shall not form any further thicknesswhich might interfere with its insertion between.

or underneath the closing parts of thebag or acket.

n the anvil carrier, the frame carrying .the means whereby the leavesare sealed, is

secured either rigidly or loosely; it may be of any suitableconstructionbut the preferable one is that the assembling of the frameand the anvil carrier shall be such that the latter shall be readilyremoved and replaced till by another carrier of a difi'erent shapehaving slmilar assembllng means. The machine wlll then comprise a serlesof anvil carriers of difi'erent shapes, interchangeable on the frame,and allowing the adapting of the niachine to the sealing of bags, boxesand packets of difi'erent kinds.

The clasps used may be of. any shape and comprise any number of claws;they may be made beforehand and supplied to the machine eitherseparately, or connected together in a continuous band 5 they may bealso sup plied to the machine 1n the form of continuous and uniformfillets and may be made on the machine itself by cutting and bendingmeans coeperating with the means serving to ve the clasps or claws intothe parts to be closed.

Another feature of the invention consists in combining with the frame asup ort specially fitted to su port the bottom 0 the bags or packetsw Iethe upper closing.-

' able, its main to be sealed above the anvil.

The frame I) is carried by upright standets. In such case, the machineW111 be preferably stationary. When it does not comprise such a su port,it may be made-portame then being adapted to be carried by hand. I

Two embodiments of this invention are shown by way of example in. theaccompanylngrdrawings, in which lgure l'is an elevation of the firstembodiment.

2 is adetail side view. 7 v

Flg. 3 1s aplan view of a bracket carrying the anvil.

Fig.4 is a plan of another bracket carry- In an anvil; and

ig. 5 is an elevation of the second embodiment. Y

In Figs. 1 to 4:, a designates an anvil hear ing bracket one end ofwhich, serving as an anvil, is provided with a recess a so shaped as tocurve the claws of the clasps and the opposite end a of which isdove-tailed to be assembled withthe main frame 6 which is provided witha slot 6 of corresponding shape; a set-screw 6 allows of rendering theanvil bearing bracket stationary on the frame I).

The means whereby the'clasps or claws are driven into the closing partsof the bags,

0 hinged at al to the frame 6, a punch g slidable in such block, aspring 0 to raise such punch and a pressure button 0 which allows oflowering the latter. The block a is normally held raised by a spring'cin order to facilitate the insertion of the parts ards d of which thelower parts are united by a base plate at intended to be secured to atable or the like.

A slide e ismovable between such standards and can be secured in anydesired position by means of a plate e and of a nut e which is screwedonto a threaded pin e of the slide. The slide 6 carries a supportingplate 6 on which the bottom of the bag or packet is enabled to rest whenthe closing part? of such bag or packet are placed on the .fiIlVl a -Theanvil bearing bracket shown in Figs.

.1 and 3 terminates in a point and its edges 20 a: vertical linecoinciding with the point of point which is to receive the clasp. Onecan also with the same device cause the anvil bearing bracket to slidebetween the lower closing part and the other closlng parts withoutpassing through any of the same.

The anvil bearing bracket shown in Fig. 4:

is of elbowed'shape which is more commodious than the straight shape forcertain kinds of packets. Its end serving as an anvil may be rounded offas shown in F1 3.

The'work support 6 exten s out beyond the member a and. thereforeconstitutes. a

gage and a gulde for the work as well as a support therefor; for whenthls member 6 has been adjusted to the proper elevatlon for operating onpackets of a given helght, the packets are each rested on the free endof the member e and then slid therealong until the proper part thereofis engaged by the point ofthe member a. Thus-all of the packets aresealed alike, and the speed of effecting the successive operations iseatly facilitated.

As will be understomi the form, the proportions and the number of. thedifferent anvil bearing brackets which can; be used with the samemachine'may be of any suitable kind.

In the embodiment shown in Fig. 5, the

main frame is curved in the shape of a neck so that it can be easil heldby the hand; the block 0 in which til mounted is incorporated with suchmain frame. As the machine is portable, the said frame does not compriseeither the baseplate or the adjustable support and the pressaid grooves,

e punch a is sure button a is replaced by a swinging lever 0 allowing ofoperating the punch with one hand while the frame is held by the otherhand; in such case, the bottom of the bag or packet may rest on a tableor other suitable support.

It is to be understood that the means whereby to drive or bend theclasps may be of any suitable kind and ma be 0 erated by hand or by footthrough t e 111 um of a foot-lever and any suitable gearing.

Claims: y

1. In a machine for fixing clasps to packets, a frame comprising ahorizontal. portion and spaced vertical portions connected at theirupper ends by said horizontal portion and providing horizontal groovesat the tops of t e vertical portions and under the horizontal portion,an anvil normally havinglone end removably fitted in said grooves anhaving its other end extending from portion to cooperate with said anvilin fixing the clasps to the packets.

2. In a machine for fixing clasps to packets,- a framecomprisinglahorizontal portion -and spaced vertical portions connectedat their upper ends by said horizontal portion and providin horizontalgrooves at the tops of the vertica portions and under the horizontalportion, an anvil normally having one end fitted in said grooves andhaving its and means on said horizontal other end extendingfrom saidgrooves, and

means on said horizontal portion to cooperate with said anvil in fixingthe clasps to the packets.

In testimony that we claim the foregoing as our invention we have signedour names in presence of two subscribing witnesses.
